WINDOW ATTACHMENT.

SPECIFICATION forming part of Letters Patent N0. 758,348, dated April 26, 1904. y Application filed December 9,1902. Serial No. 134.485. (No model.)

To all when?l t may GoT/warn,.-`

Be it known that I, LUDWIG K. BHM, acitizen ofthe United States of America, and a resident of Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Window Attachments, of which the `following is a specification. A

This invention has reference to window at- Io tachments, and relates particularly to attachments which ventilate the room and keep same at the desired temperature.v

The attachment is applied to the bottom rail of the window-sash and to the lower portion of the stop-bead on the window-sill.

A special feature of this invention is that the attachment may be inserted to any Window and removed when it is not desired to use same.

zo Another feature of this novel attachment is that no draft is created when same is employed. n

The device further is so plain in construction that it can be manufactured very cheaply.

2 5 The removal of the attachment is very easily effected. It may be done by any one-say a member of the family-because no tools are required for removing same. e

The air admitted to the room when the attachment is employed will enter between the meeting-rails of the Window. A't the same time no air will be admitted below the bottom rail of the window-sash, and the upper half of the window will remain in its usual 3 5 closed position. When the device is operated, theL lower half of the window is raised,

admitting cool air between the meeting-rails.

In this kind of devices various advantages will be gained for the following reasons: The

40 air naturally enters* in an upward direction,

and as there is quite a distance between the meeting-rails and the ceiling the air moves in its upward direction until it strikes the ceiling,` from whence it gradually descends after' having its velocity reduced to some extent by this circuitous course. Thereby the temperature in the room is lowered and the room ventilated without causing any draft, and particularly the feet of occupants of the room never grow cold. W'hen airis admitted be- 5C? low the bottom rail, then draft is unavoidable. Likewise when air is admitted above the top rail draft is created, because the rushing-in air strikes the ceiling too quickly and is thrown down directly.

The invention is illustrated in the accompanying drawings, in which- Figure lv is a front elevation of a Window with the attachment applied thereto embodying my invention. Fig. Qis a horizontal sec-4 60 tion on line 2 2 of Fig. l. Fig. 3 is a vertical cross-section on line 3 3 of Fig. 2. Fig. t is a vertical cross-section showing a modiication of the attachment. Fig. 5 represents in vertical cross-section a modified guiding device. Fig. 6 is a horizontal section of the device shown in Fig. 5; and Fig. 7 illustrates in section the side wall of a stock-car, showing the attachment applied thereto. VFig. 8 is a front elevation of the modification shown 76 in cross-section in Fig; 4:, wherein a telescoping member is employed in lieu of the single board.

Similar letters of reference 'denote like parts in all the ligures. 75

In the drawings, a represents the window, and the attachment applied thereto is designated by the letter The attachment t consists cfa board with means to secure same on the stop-bead d and the `window-sill. There are, 30 further, guiding means on the bottom rail c of the window-sash which permit of raising the lower halfof the Window up on the attachment 5. The attachment lits between the stop-beads ai d' on the sides of the window-,85 frame without being secured thereto, so that the width of the attachment is less than the width of the window-sash, because part of the side rails e c of the sash is, as usual, cov-f ered by the window-frame and stop-bead d 9G and the easement f. The attachment Z) need not be very thick.' However, itmust be thick enough to apply therein the means for permitting of sliding the bottom rail up and down thereon. 95

Various means may be employed for securing the attachment to the stop-bead and the window-sill, vand various devices may be used for guiding the bottom rail up on the attachment. In Figs. 1, 3, and 4 the attachment is secured by plain pins g, which pass'through the stop-bead and the attachment, asis shown in Figs. 3 and 4. The pins are easilyinserted and removed, so that the attachment may be easily applied and taken out.

The bottom rail-guiding device tin Figs. 1 and 2 is shown to consist of angular grooves z', contained in the attachment near the ends of same. The groove e' is widenon the inside, and a similarlyshaped strip of wood or metal secured to the bottom rail slides in the groove 't' when the window is raised or lowered. The strip is permanently secured to the bottom rail c and remains there when the attachment is removed. As is shown in Fig. l, the attachment isof same height as the bottom rail, and necessarily the groove i and the strips 7c are of same length.

A modification of the guiding device is shown in Fig. 5. It consists of a circular groove Z, contained in the attachment, and a metal rod m, secured to the top portion of the bottom rail c.

As above stated, the attachment is of same height as the bottom rail of the sash. It' it is desired to increase the height of the attachment, then a second board b is employed same as the iirst, and both are secured to the stopbead, asis shown in Fig. 4. In this instance the board adjoining the bottom rail is provided with a tongue u on each side near its top ends. Each tongue has an opening which coincides with a like opening in the bottom rail, so that a pin 0 may be inserted in each set of openings. Assuming now that this be done, then the pins g, retaining the boards in the stop-bead, are drawn out a little, so as to hold only the board 7), which adjoins the board Upon raising now the lower half of the window the board b/ adjoining the bottom rail will be raised with same, because it is secured in the described manner to the bottom rail. It may be raised to fully twice the height of the bottom rail, if it is desired to do so.

The, attachment may be applied to any kind of sliding windows in all kinds of buildings, in railroad-cars, and particularly in stockcars. In closed stock-cars the animals, particularly horses, suffer a great deal from draft during transportation. Horses easily contract pulmonary diseases and get stiff limbs lfrom the draft during long journeys on the road because it is impossible to keep them in the same atmosphere, and ventilation is absolutely necessary. By the use of my novel attachment no draft is created in the stock-cars, and the animals remain perfectly healthy. Fig. 7 shows a section through the side wall of a stock-car with the attachment applied. A

narrow side board p is shown in this figure lo-l cated on the side of the window and reaching above the meeting-rails up to the top of the window. This is done because the cars are rather low in comparison to the height of the horses,and by the application of such boards on each side of the window no. rushing-in air will reach the heads of the horses. The hooks for raising the window necessarily are located on the lower portion of the side rails of the window-sash, as is shown in Fig. l.

It is plainly seen that no devices are necessary for regulating the ingress of the air when my attachmentis employed. The lower half of the window maybe raised fromatriiie to the full height of the bottom rail, thereby regulating the ingress of the air without any special devices.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- 1. The combination with a window, of a board removably secured to the stop-bead of a window-sill between the stop-beads on the sides of the frame, and means for holding the board in contact with the lower rail of the window-sash, whereby the sash may be raised and air prevented from entering beneath the lower rail.

2. In a device of the class described, the combination with a window, of a board removably secured to the window-sill and having a vertical groove therein, pins in the window-sill engaging the board to hold the latter to the former, and a strip on the bottom rail of the window-sash adapted to engage and slide in the groove in the board, whereby the window- 'sash may be raised or lowered and air prevented from entering beneath the lower rail of the sash.

3. In a device of the class described, the combination with a window, of a board removably secured to the stop-bead on the window-sill and having two vertical undercut grooves therein, pins mounted in the stop-bead and engaging the board, and strips secured to the bottom rail of the window-sash, said strips engaging the grooves in the board and having their sides diverging outwardly to correspond in shape to the grooves in the board, whereby the board is interlocked with the lower rail of the sash and the latter permitted to be raised or lowered.

4. In a device of the class described, the combination with a' window, of means to prevent a draft beneath the lower rail of the sash when the latter is raised comprising a board removably secured to the window-sill and disposed parallel with the sash and having an interlocking sliding engagement with the sash.

5. In a device of the class described, the combination with a window, of means to prevent a draft beneath the lower rail of `the sash when the latteris opened, comprising two boards secured 'to the stop-bead onv the window-sill between the stop-beads on the sides of the window-frame, pins mounted in the stopbead of the window sill and engaging the IOO boards, oneV of said boards having an-interlooking engagement with the lower rail of the window-sash and adapted to be carried thereby when the sash is raised.

6. The combination Witha Window having its lower sash provided with doveteil strips extending vertically on the lower rail thereof, ofa board mounted on the Window-sill contiguous to the lower rail of the sash and provided with dovetail grooves which ereslidably engaged by the strips on thesash, tongues on the top of the board having openings therein,

pins tting in said opening and engaging theY sash to lock the board to the sash, a second board in mutual Contact With the lirst-Inen- I5 LUDWIG K. BHM.
